Abstract
Computer calculations of slope effects on surface noise at 100 Hz were made using the NORDA high‐angle, implicit finite difference acoustic field model. A geoacoustic description of a continental margin, which is typical of the east coast of the U.S., was chosen for analysis (vertical slope of 2.8 deg and covered by 500 m of silt). In order to enhance the effect of bottom interaction, a Summer Sargasso Sea sound‐speed profile was used. The calculations indicate the presence of a deep noise notch over the slope (for certain basin and shelf noise generating locations) which is deepest near the ocean surface (25 dB) and which decays with depth. The potential for signal‐to‐noise ratio gain is suggested. [Work supported by NAVAIR.]
